Materials, Craftsmanship, and Market Data for Queen's Crowns

The British Crown Jewels use a gold alloy with a purity of 22 karat, while the French Crown of Napoleon III used platinum settings for its diamonds, reflecting a shift in metallurgy during the 19th century. Gemstone valuation follows the 4C standard for diamonds and country-of-origin premiums for colored stones. The Hope Diamond, a 45.52-carat blue diamond, is valued at over 250 million USD, and similar stones set in crowns directly inflate their replacement cost GIA.
